Move a layer

The postition of a layer in the layer tree determines the rendering order. That is, the non-group layers are rendered in order of a Depth-first traversal of the layer tree. The toplevel group layer is called 'root'.

l_layer_move(widget, layer, parent, index = "0")

Arguments

widget	widget path or layer object of class 'l_layer'
layer	layer id. If the widget argument is of class 'l_layer' then the layer argument is not used
parent	if parent layer is not specified it is set to the current parent layer of the layer
index	position among its siblings. valid values are 0, 1, 2, ..., 'end'

Value

0 if success otherwise the function throws an error
